Capacity build-up to force volumes west…even from Asia?

There’s been a lot of talk about the next wave of Middle East capacity being too great for Asia to absorb all the Asian volumes. Indeed, estimates abound over western growth being satisfied by the M-E over the next 3-5 years.

A case in point are these claims from expandable polystyrene producers that they even expanding to serve the European market, never mind just shifting volumes that used to go to China.
